[RE-wrenches] Wattsun AZ-225 reliability and Production

[Drake Chamberlin]

It is great to hear that Wrenches are having better luck with 
trackers.  This recent thread, on the subject, is way different that 
what has been stated in the past.  It sounds like trackers might 
really be a cost effective approach to net metering.  Is it really 
more cost effective than adding more modules, as we had figured in the past?
